Can Someone Clarify...

What is the difference between "populism" and "fascism by the majority"?    I sure can't see any difference.

I love it when I see stuff like "take on the oil companies" or "take on the drug companies."  The oil companies make about an 8% profit in a good year.  Drug companies are a bit higher, but not that much.  Let's say the government runs their profit down to zero.  That would then yield everyone about a 6% discount at the pump (presumably gas taxes would not go down, thus the lower percentage) and an average 12%-ish discount on drugs.  Is it really the Democrat's intention to trash incentives in these critical industries for future long term investment (oil exploration in one, drug R&D in the other) so politicans can hand out a 6% discount to the voters?
